Designers of compact, complex electronics require robust interconnection methodologies. The stacked microvia HDI PCB provides a highly efficient build-up structure, enabling vertical integration of multiple microvias across consecutive layers. This architecture significantly increases routing density, accommodates fine-pitch BGA components, and optimises signal integrity in miniaturised devices.
Key Features of the Stacked Microvia HDI PCB
-
Advanced Stackup Architecture: 1+N+1, 2+N+2, 3+N+3, and any-layer HDI configurations available.
-
Copper-Filled Microvias: Ensures robust electrical connections and efficient thermal dissipation between layers.
-
Fine Line and Space Capability: Trace widths and spacing down to 2 mil / 2 mil (50 µm / 50 µm).
-
Dielectric Materials: Compatible with standard FR-4, high-Tg FR-4, halogen-free, and high-frequency laminates (e.g., Rogers, Isola).
-
Surface Finish Options: ENIG, ENEPIG, Immersion Silver, and Immersion Tin for reliable component soldering.
-
Stringent Manufacturing Standards: IPC-A-600 Class 2 and Class 3 compliant.
